407 Proxy Authentication Required
What it means: Your credentials are incorrect or missingCommon causes
Common causes
- Wrong username or password
- Credentials not properly formatted
- Extra spaces in credentials
- Password changed in dashboard but not updated in code
- Special characters not URL-encoded
Solutions
Solutions
1. Verify credentials in dashboardGo to Dashboard → Settings and copy fresh credentials2. Check for extra spaces3. URL-encode special characters4. Test with curl
403 Forbidden
What it means: Access denied to the resourceCommon causes
Common causes
- IP whitelist enabled but your IP not added
- Insufficient balance
- Target website blocking proxy IP
- Country/city not available in your plan
- Proxy type not allowed for your account
Solutions
Solutions
1. Check IP whitelistIf IP whitelisting is enabled:3. Try different proxy parameters4. Check target websiteSome sites block all proxies. Try:
- Get your current IP:
curl https://api.ipify.org - Add it in Dashboard → Settings → IP Whitelist
- Different session ID (new IP)
- Different proxy type
- Web Unlocker instead
429 Too Many Requests
What it means: Rate limit exceededCommon causes
Common causes
- Too many concurrent requests
- Requests sent too quickly
- Target website rate limiting
- Exceeding plan limits
Solutions
Solutions
1. Add delays between requests2. Implement exponential backoff3. Use rotating sessions4. Check concurrent requestsReduce number of parallel requests if using async/threading
502 Bad Gateway
What it means: Target server returned invalid responseCommon causes
Common causes
- Target website is down
- Target blocking proxy IPs
- Network issue between proxy and target
- Target website maintenance
Solutions
Solutions
1. Verify target site is upCheck if the website works in your browser without proxy2. Try different proxy type3. Use session parameter4. Consider Web UnlockerFor protected sites, use Web Unlocker API instead:
504 Gateway Timeout
What it means: Request took too long to completeCommon causes
Common causes
- Target website slow to respond
- Network congestion
- Complex page rendering
- Timeout set too low
- Slow proxy location
Solutions
Solutions
1. Increase timeout2. Try different proxy location3. Use datacenter for speed4. Set separate connect and read timeouts
Connection errors
Connection Refused
What it means: Can’t connect to proxy serverCommon causes
Common causes
- Wrong host or port
- Firewall blocking connection
- Network issue
- Typo in proxy URL
Solutions
Solutions
1. Verify host and port2. Check available ports4. Check firewallEnsure your firewall allows outbound connections on port 10080
- HTTP:
10080 - HTTPS:
10443 - SOCKS5:
10800

Captcha / Challenge
What it means: Target detected automationSolutions
Solutions
1. Use residential or mobile proxies2. Add realistic headers3. Add delays4. Use Web UnlockerWeb Unlocker automatically handles captchas:
IP Blocked
Signs: 403 errors, blank pages, infinite redirectsSolutions
Solutions
1. Force per-request rotation2. Try different proxy type3. Add delays between requests4. Use different sessions
Session issues
Session Keeps Expiring
Why this happens
Why this happens
Sessions expire after 10 minutes of inactivity
Solutions
Solutions
1. Send keepalive requests2. Use a static IP insteadFor long-running sessions, use a static IP returned by the Static IP List endpoint:
IP Not Changing
Why this happens
Why this happens
You’re using a session parameter
Solutions
Solutions
1. Remove session parameter2. Change session value3. Force rotation

FAQ
How do I check my balance?
How do I check my balance?
What ports should I use?
What ports should I use?
- HTTP:
10080(default, recommended) - HTTPS:
10443 - SOCKS5:
10800
Can I use the same session across different devices?
Can I use the same session across different devices?
Yes! The session is tied to the session ID in the username, not to your device.
Why am I getting different speeds?
Why am I getting different speeds?
Speed depends on:
- Proxy type: Datacenter > Residential > Mobile
- Location: Closer proxy = faster
- Network congestion: Varies by time
- Target website: Some sites are just slow
How many concurrent connections can I use?
How many concurrent connections can I use?
Depends on your plan. Check limits:Or contact support for custom limits.
Can I whitelist IPs?
Can I whitelist IPs?
Yes, in Dashboard → Settings → IP WhitelistWhen enabled, only whitelisted IPs can use your proxies.
What's the difference between rotation--1 and rotation-0?
What's the difference between rotation--1 and rotation-0?
rotation—1 means
rotation=-1 in the builder API:- New IP every request
- Best for broad scraping where identity stability is not needed
rotation=0 in the builder API:- Keep the same IP within a session
- Best for login, checkout, or other multi-step flows
